A portable electronic apparatus and an interactive human face login method are disclosed. The portable electronic apparatus comprises a face database, a user interface, an image capturing device, and a recognition circuit. The face database stores a plurality of facial expression feature information. The user interface randomly generates a plurality of facial expression indications used for guiding a user to sequentially show a plurality of facial expressions. The image capturing device captures the facial expressions to output a plurality of facial expression images. The recognition circuit receives a login request and determines whether the facial expressions are consistent with the facial expression indications according to the facial expression feature information and the facial expression images. The login request is allowed if the facial expressions are consistent with the facial expression indications.

A method for controlling an exposure duration of a high dynamic range image, including: consecutively generating a first high dynamic range image having a first exposure duration ratio and a second high dynamic range image having a second exposure duration ratio greater than the first exposure duration ratio; performing image quality evaluations on both the first high dynamic range image and the second high dynamic range image to obtain a first image quality and a second image quality, respectively; and determining whether the second image quality is better than the first image quality; if yes, generating a third high dynamic range image having a third exposure duration ratio greater than the second exposure duration ratio; if not, generating the third high dynamic range image having the first exposure duration ratio and setting the first exposure duration ration as the optimal exposure duration ratio.

A virtual control device is provided for an electronic device. The virtual control device includes a first lens, a second lens, a first photosensitive unit, a second photosensitive unit and a processor unit. The first photosensitive unit is arranged behind the first lens by a focal length, and obtains a first image via the first lens. The second photosensitive unit is arranged behind the second lens by the focal length, and obtains a second image via the second lens. The processor unit determines the object-position coordinates of a virtual control plane according to a first position of the projection of the object on the first photosensitive unit and a second position of the projection of the object on the second photosensitive unit, and the processor unit provides the object-position coordinates to the electronic device.
